44 / 72 page  8 Channel Capacitive Touch Sensor with 8 LED Drivers Datasheet Revision 1.1 (08-05-09) 44 SMSC CAP1088 DATASHEET APPLICATION NOTE: The programmed cycle time is only maintained if the total averaging time for all samples is less than the programmed cycle. The AVG[2:0] bits will take priority so that if more samples are required than would normally be allowed during the cycle time, the cycle time will be extended as necessary to accommodate the number of samples to be measured. 5.11 Calibration Activate Registers The Calibration Activate register force the respective sensors to be re-calibrated. When a bit is set, the corresponding Capacitive Touch Sensor will be re-calibrated and the bit will be automatically cleared once the re-calibration routine has finished. During the re-calibration routine, the sensors will not detect a press for up to 600ms and the Sensor Base Count register values will be invalid. During this time, any press on the corresponding sensors will invalidate the re-calibration. Bit 7 - CS8_CAL - When set, the CS8 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 6 - CS7_CAL - When set, the CS7 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 5 - CS6_CAL - When set, the CS6 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 4 - CS5_CAL - When set, the CS5 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 3 - CS4_CAL - When set, the CS4 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 2 - CS3_CAL - When set, the CS3 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 1 - CS2_CAL - When set, the CS2 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 0 - CS1_CAL - When set, the CS1 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully.
